irk miller said:At Vintage Brake, he says the perfect feel for a twin caliper brake has a ratio of 27:1. Your AP brake has (2) 43.1mm pistons, so according to his chart, that's 11mm. 23:1 will give you a firm brake, which is probably what Willi likes @ 12mm. The issue with the larger bore is that you won't get any brake until the wheel locks up.
My bad. I thought we were talking about the OP's AP Racing twin caliper in this pic:doc_rot said:they're opposed piston calipers so there's 4 live pistons for a dual caliper setup. also the correct size is 41.3mm pistons. 16mm is the correct size as with a 41mm piston that puts the ratio at 26.7. As I said i run Grimeca copies of these calipers and have great brakes with a 16mm MC. I also run a 12mm on my single caliper brembo replica and that works well. the advantage the Brembo or Grimeca has over the Lockheed is they can accommodate a larger diameter disk. The Brembos are the nicest as far as fit and finish of the three.
